Justification:
Wilson's Winter Katydidis considered of Least Concern because, although it has a relatively small extent of occurrence (~18,000 km2), it is known to occur within at least 13 locations, and is not expected to experience imminent population or habitat decline. This species is endemic to two sensitive biodiversity hotspots, the Cape Floristic Region and Succulent Karoo, which makes it of interest, but it is commonly encountered and found within at least two protected areas, Hantam National Botanical Garden and Maskam Nature Reserve, so it does not immediately require any conservation actions. Public participation in the website iSpot led to the addition of four locations and doubled the known extent of occurrence of the species, illustrating the potential positive contribution of such platforms for assessing species' distributions. The genus Brinckiella experienced an adaptive radiation in the Fynbos and Succulent Karoo biomes of Western and Northern Cape Provinces, South Africa, with at least 9 species known in a relatively small geographic area.

This species occurs within the Fynbos biome and is abundant in arid proteoid fynbos between Citrusdal and Clanwilliam, Western Cape. It is also known to occur in the southern Northern Cape Province, in the transition zone from Fynbos to more arid Succulent Karoo.

No specific conservation measures are in place for this species. The species is known to occur in Hantam National Botanical Garden and in Maskam Nature Reserve, both in Northern Cape Province, and is also expected to occur within the Cederberg Wilderness Area, Western Cape Province, South Africa.
